All Flashcards

Define electric potential energy ( $U_e$ ).

The energy a charge possesses due to its position in an electric field.

Define electric potential (V).

Electric potential energy per unit charge; the 'push' available to move a charge.

What are equipotential lines?

Lines or surfaces where the electric potential is constant. No work is done moving a charge along them.

Define 'work' in the context of electric forces.

Work is done when moving charges in an electric field, overcoming the electric force.

What are Volts (V)?

The unit of electric potential, equivalent to Joules per Coulomb (J/C).

What are the key differences between electric potential energy ( $U_e$ ) and electric potential (V)?

$U_e$ : Energy (Joules) | V: Energy per unit charge (Volts)

Compare the equations for Work ( $W$ ) and change in Electric Potential Energy ( $Delta U_e$ ).

$W = \int F cdot dr$ or $W = Fd\cos(\theta)$ | $W = -\Delta U_e$

For a point charge, what is the shape of equipotential lines?

Concentric circles centered on the charge.

What is the relationship between electric field lines and equipotential lines?

Electric field lines are always perpendicular to equipotential lines.
